Self-consumption rate with battery
A solar panel system without battery storage exports surplus electricity to the grid at low SEG rates (typically 3–15p/kWh) and then buys electricity back in the evening at full retail price (24–28p/kWh). A battery closes this gap by storing your own solar electricity for use when the sun is not shining.
With a battery, a typical 4kW solar system with 9.6kWh storage can achieve 80–90% self-sufficiency throughout summer months, dramatically reducing grid imports. The additional cost of a battery is typically recovered in 5–7 years through avoided import costs.
All prices include installation and 0% VAT. Supplied and installed by Midland Solar.
